'1 Claims. (01. 294-44) (Granted under the... of March a, 1883. as amended April so, 1928; :70 o. G. 157) The invention described herein, if patented, respectively, of a slight modification of the may be manufactured and usedlby or for the clamp. 1 Government for governmental purposes, without Reference now being had to the drawings by the payment to me of any royalty thereon. numerals: l and 2 indicate respectively, lower This invention relates to an improved cable 5 and upper cable-clamping jaws, provided with clamp, and more particularly to a clamp adapted longitudinal grooves 3 and 4, said jaws are arto be quickly adjusted on a cable to the desired ranged in parallel relation with the cable restposition and form an immovable anchorage ing therebetween in their respective grooves. thereon, automatically locked in position by com The lower jaw I is provided preferably at 9.

necting a free end of the cable, after engage p ion intermediate f h endS 01 its r ve ment with a load, to the clamp. with a cutaway or depressed portion 5 adapted The objects of this invention are to provide a in cooperati m w h a projecting or ridge portion simple, durable and inexpensive device of the l-in the groove of the upper jaw to cause a slight class described; simple in construction and opbend in the cable as the jaws are drawn toeration, wherein the use of the device will be Ward each other. and thus add to t ripp apparent at a glance, there being no complicaeffect of the clamp on the cable. The lower jaw tion of parts to confuse its proper operation by is further provided, if preferred, with serrations those of practically no mechanical skill; duror transverse teeth I in the face of its groove able, due to its sturdy construction along the meet as further means for anchoring the clamp lines of its greatest strains, without unnecessary to the cable.

duction, namely, forging of the parts that may metal where not needed, and inexpensive, due to A jaw-clamping loop 8 surrounds the jaws the above and the methods required in its protransversely at approximately their centers, is mounted on the lower face of the lowerjaw in a seat 9' formed between projections llii0.

The loop I snugly fits around the jaws, is mounted for swinging movement at its lower end in the seat 9, and extends a short distance above the upper jaw, the distance the loop 8 extends above the upper jaw is important and will be referred to morefully later.

Connected to the jaw-clamping loop is a link ll adapted to swing the loop 8 to one side or the other of a transverse position directly across the laws in either of which positions the link will be brought into contact with the upper face of be accomplished at a very high rate with comparatively low cost machines.

The above and other objects and advantages of this invention will appearin the following description and befinally pointed out in the claims.

A preferred embodiment of the invention is shown, but it will be understood that slight changes in form and minorv details in construction may be resorted to without departing from the spirit of the invention, or fall beyond the scope of the claims.

Similar numerals indicate corresponding parts in all the figures of the drawings in which,

around the load I! and thence back, and is connected to the link ll.

It will be noted that the distance between the the upper jaw in such a manner as to exert a very cable after it has pressed through the clamp,.

Fig. 4 is an enlarged longitudinal section of th clamp with parts in dotted positions.

Fig. 5 is an enlarged plan view. Fig. 6 is an end view.

Fig. 7 is a transverse section on line 1-1 of Fig. 4.

Fig. 8'shows perspective views of the adjacent faces of the clamping jaws.

Figs. 9, l0, and 11 are side, top, and end views,

top of the upper jaw and the link II, when the loop 8 is resting directly across the jaws, is slightly less than the depth of seat ii at the lower end of the loop 8, thus permitting free adjustment of the clamp on the cable, but preventing the loop leaving its seat prior to tension being applied to the link.

To insure against'the separation of the parts of the clamp and should, for instance, it is desired to store the clamp and cable separately,

or for other reasons to separate the cable and clamp, a slight modification or the clamp as shown in Figs. 9, 10, and 11 may be provided wherein lugs l4 extending from the ends or one or the jaws, adapted to operate in cutout portions IS in the end of the other jaw are adapted to prevent relative 'tramverse or longitudinal movement of the jaws.

There may also be provided buttons l formed by riveting pins through the lower jaw on opposite sides of the clamping loop which will entirely eliminate the accidental separation of the four elements of the clamp, namely, the jaws, the clamping loop, and the clamping loop operating link.

While the free end of the cable, after passing grooves, said grooves provided with means for around the load, may be secured to link H in any preferred manner, for the purpose of accomplishing the prompt and effective connection of said parts, a hook I! securely mounted at the end of the cable is provided.

The operation of the clamp is obvious and provides clamping jaws between which the cable is extended, a free end of the cable may then extend around the load and back to thelink of the clamp. When power is applied to the other free end of the cable, tension will be applied to the parts in sucha manner as to swing the loop diagonally across the'jaws and close them on the cable, thus effecting a firm anchorage of the clamp on the cable and maintain the loop as originally adjusted. On the other hand should, ,for any reason, slack in the loopof the cable develop, the tension on the link will be diminished,

, the power will draw the cable through the clamp,

forming a slight bend in the cable, ,a jaw-clamping loop surrounding the jaws and a link connected with the loop adapted to rock the loop, draw the jaws toward each other, and clamp the cable.

5. The combination with a cable of a cable clamp comprising, cable-clamping jaws having grooves provided with a depression and an extension in the grooves adapted to coact to form a slight bend in the cable and more firmly grip the cable, a jaw-clamping loop surrounding the 'jaws and a link connected with the loop adapted when connected, to a free end of the cable after extending around a load to rock the loop, draw the jaws toward each other, and clamp the cable.

6. In a cable clamp, the combination of opposed jaws, a centrally located jaw-clamping loop loosely seated at its end on one of the jaws, and extending transversely around and beyond the opposed jaw, a clamping loop operating link mounted in the extended end of the loop adaptthe slack about the load will be taken up and the jaws will at once again grip the cable.

I claim: 1. The combination with a cable of a cable clamp comprising, cable-clamping jaws adapted to receive the cable therebetween, a jaw-clamping loop surrounding the jaws and a link connected with the loop adapted when connected to a free end of the cable to rock the loop, draw the jaws toward each other, and clamp the cable.

2. The combination with a cable of a cable clamp comprising, cable-clamping jaws adapted to receive the cable therebetween, a jaw-clamping loop surrounding the jaws mounted on the lower jaw adjacent to the center thereof, and a link connected with the loop adapted when connected to the cable to rock the loop in either direction to draw the jaws toward each other and clamp the cable.

ed to operate the clamping loop to either side or directly transverse of the jaws and secure the clamp to a cable after the cable has passed through the loop around a load, and is secured to said loop operating link.

7. A cable clamp comprising, opposed cableclamping jaws adapted to adjustably receive a cable therebetween, a jaw-clamping loop centrally and transversely surrounding the jaws adapted when rocked into a position from a line directly around the jaws to draw the jaws toward each other and clamp the cable, and a link mounted in the loop adapted to be connected with a free end of the cable after it has passed around a load and is attached to said link to securely retain the cable in its adjusted position on the cable.
